245/40/18 OK for the rear?

maxslug · 03-20-2013, 01:24 PM

Hi All,

I just ordered some new Dunlop Direzza ZII's (Star Spec v2)'s for my N55 135i. It's got the M-sport 18's.

I wanted to get something more square to reduce understeer, so I got 225 front, and 245 rear. The stock rear is a 255/35/18, however they don't make a 245/35/18 so I got a 245/40/18.

Does anyone know if I'll have any problems with the slightly taller tire?

Thanks,

For googlers of the future -- this worked fine so far, seems to be plenty of clearance, no rubbing. Speedo is fine too, off by about 1mph when compared to my phone's GPS when on cruise control.

Not sure how this would be if the car were lowered more.
